SUMMARY
Investor apprehensions surged as questions arose about the viability of massive AI investments. Consequently, investors chose to rotate their investments from the trending AI-led ecosystem, tech and chip stocks, to defensive bets in the consumer, retail, and financial sectors.

The US market's earnings season is turning out to be quite eventful, with megacap earnings surprising on the downside. After a slew of megacap earnings this week, the US benchmark indices turned lower on Wednesday and Thursday. The NASDAQ 100 futures further fell over 1.4% on Friday morning, as overnight earnings releases indicated weakness and disappointment against expectations. The September quarter earnings have largely remained muted for tech companies, delivering below-estimate top-line and bottomline performance.
Besides this, investor apprehensions surged as questions arose about the viability of massive AI investments. Consequently, investors chose to rotate their investments from the trending AI-led ecosystem tech and chip stocks to defensive bets in the consumer, retail, and financial sectors. The tech-heavy NASDAQ 100 index plunged 3.3% in October, after touching fresh record highs. On the flip side, the Dow Jones surged 2.8% for the month, amid bargain hunting in the defensive stocks in the Dow Jones index.
The NASDAQ’s loss was largely led by semiconductor and tech stocks, which fell in high double digits in October. The major losers for this month in the semiconductor industry included names like Intel Corporation (-21%), Marvel Technology (-15.5%), Micron Technology (-13.3%), Advanced Micro Devices (-8.1%), NVIDIA (-7.4%), and Broadcom (-3%). Among the megacap names, Alphabet plunged over 16% this month, followed by Meta Platforms at -14%.
On the other hand, shares of retail and consumer-focused companies like Home Depot (+13%), Walmart (+12%), McDonald's (+10.8%), Procter & Gamble Company (+8.5%), Coca-Cola Company (+7.2%), and Nike (+5.2%) were the top gainers this month. Apart from these, shares of financial services names like Visa Inc (+11.9%) and American Express Company (+5.4%) also surged this month. Investors chose sectoral rotation from overheated technology stocks to defensive bets in retail, consumption, banking, and financial services.
The apprehensions over overheated valuations in the technology and semiconductor space are growing day by day as the companies fail to deliver any meaningful outcome on the massive AI-led capex investments.
The US stock markets trade at an inflection point where the tech companies have to invest heavily to run the AI operations until it delivers meaningful outcomes, at a time when the cost of capital rises to multi-year highs. Investors are now increasingly turning away from investing incrementally into the AI theme, which is generating negative cash flow with heavy investments and rotating their investments into positive cash flow defensive bets in the consumer, retail, and financial services sectors.
